Moving Magnet Galvanometers. 



All mirror galvanometers are fitted with simple plane mirror unless otherwise specified. 

 If specially ordered, and at an extra cost, we can insert a polished plane mirror or a concave 

 mirror for scale-reading apparatus for 1 or 2 metres distance. In the latter case the 

 distance desired should be stated.
